If sybmigrate fails unexpectedly, clean up the source and target Adaptive Servers, and begin migration again. There are actions that you must perform on both the source and target Adaptive Server.
On the source Adaptive Server:
Drop the temporary working databases mtpdb$%.
Drop the repository database sybmigratedb.
Drop all remote servers mtrs$%.
On the target Adaptive Server:
If server data was migrated, rebuild the target Adaptive Server with srvbuild or syconfig.
Re-create the target databases.
